At the event mentioned before http://www.swib09.de/programm.pdf today CIDOC CRM has been presented in detail, though it seemed that a SKOS application is not available yet. See also the tweets http://twitter.com/search?q=%23swib09 , with a fair amount in English. One presentation was about the Europeana project, which among others works on SKOS-encoded information for providing thesaurus- or faceted-browsing search functionalities. I would recommend you to contact Stefan Gradmann stefan.gradmann@ibi.hu-berlin.de if you want to get more details and the state of implementation.
